CHARLES L. BETTS, OF NEW YORK, N.

OF NEW YORK, K. Y.

LANTERN-TUBE.

To all whom it may concern:

Be it known that l, Crranrns L. Bn'rrs, a citizen of the United States, residing at New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Lantern-Tubes, of which the following is a specification.

This invention relates to that class of lantern tubes in which each tube is composed of halves which are secured together or joined lengthwise on the inner and outer sides of the tube, each half being stamped out of a blank of tin or other sheet metal.

The object of the invention is to provide this class of tubes in a simple and inexpensive manner with strong and durable bearings for the ends of a bail which is attached to the same by closed eyes, whereby a secure and reliable attachment of the bail to the lantern tubes is established.

In the accompanying drawings: Figures 1 and 2 are outside elevations of the upper portions of the separate halves of a tube pro vided with this improvement. Figs. 3 and l are vertical sections in lines 3-3, Fig. l, and 4-4, Fig. 2, respectively. Fig. 5 is a vertical section through the bail ear, showing the halves of the tube assemblec Fig. 6 is a similar view showing an eyelet secured to the bail ear. Fig. 7 is an elevation of theupper portion of the tube. Fig. 8 is an end view of the tube, showing the bail connected with the ear.

Like reference characters refer to lik parts in the several figures.

A and B represent the half tubes, each of which is of usual construction in its general features and comprises an upright body. portion 20 and an upper elbow portion 21. These half tubes are half round in cross section and are provided along their inner and outer edges with longitudinal flanges 22 23 and 24 25, respectively, by means of which the halves are securd together in a well known manner, the flanges 24 25 of the half tube B being wider than the flanges 22 and 23 of the half tube A and bent around the same.

The half tubes are provided in corresponding places at their outer edges with projecting ears 26 27, respectively, for the attachment of the bail. The ear-27 of the half tube B is preferably so long or high that it can be bent or folded around the top edge of the ear Specification of Letters Patent.

26 of the half tube A, as represented in Figs. 5 and 6, thereby giving the compound ear formed by the ears 26 27 increased strength and a nice finish. The compound ear so formed projects from the closed tube fiatwise in the plane of the oint and is provided with a transverse perforation in which an eyelet 28 is secured which secures the three thicknesses of the compound ear securely togetherand also forms a bushing for the eye 29 at the end or the bail. As the compound ear is connected at its base to the closed tube and is located outside of the same and projects liatwise from the tube in the plane of the joint, the eye of the bail can be closed 1 ightly after having been engaged with the 1 ear, thereby establishing a permanent and durable connection of the bail with the ear.

I claim as my invention:

1. A sheet metal tube composed of half tubes which are joined lengthwise on their inner and outer sides and are provided at their contiguous outer edges each with a flat projecting ear, said ears lying against each other when the tube is closed and forming together a flat compound ear which is connected at its base with the closed tube and projects outwardly from the latter and is exposed on both sides and provided with a perforation for the reception of a bail ex tending transversely through the ear, sub stantially as set forth.

2. A sheet metal tube composed of half tubes which are joined lengthwise on their inner and outer sides and are provided at their contiguous outer edges each with a flat projecting ear of different length, said ears lying against each other and the longer ear being folded around the shorter ear and forming therewith a flat compound ear which is provided with a transverse perforation for the reception of a bail, substantially as set forth.

3. A sheet metal tube composed of half tubes which are joined lengthwise on their inner and outer sides and are provided at their contiguous outer edges each with a flat projecting ear, said ears lying against each other when the tube is closed and forming together a flat compound ear which is connected at its base with the closed tube and projects outwardly from the latter and is 5 exposed on both sides and provided with a j perforation for the reception of a bail eX- which is provided with e transverse pertormtion for the reception of a, bail and with an eye secured in said perforation, substantially as set forth.

Witness my hand in the presence of two subscribing witnesses.
